OSID - osid.recognition.ConvocationLookupSession Service Interface Definition

Interface	osid.recognition.ConvocationLookupSession
Implements	`osid.OsidSession`
Description	This session defines methods for retrieving convocations. This lookup session defines several views: comparative view: elements may be silently omitted or re-ordered plenary view: provides a complete result set or is an error condition isolated academy view: All convocation methods in this session operate, retrieve and pertain to convocations defined explicitly in the current academy. Using an isolated view is useful for managing convocations with the `ConvocationAdminSession.` federated academy view: All convocation lookup methods in this session operate, retrieve and pertain to all convocations defined in this academy and any other academies implicitly available in this academy through academy inheritence. active convocation view: All convocation lookup methods return convocations where the convocation is active. any status convocation view: Convocations of any status are returned. The methods `useFederatedAcademyView()` and `useIsolatedAcademyView()` behave as a radio group and one should be selected before invoking any lookup methods.
